This a long standing site with a stable Oracle infrastructure. Development is done on a full WL suite by one of 2 developers, depending on external resource availability. The original installer who is one of the developer has recently found that every time he opens any Canvas on any Form the system hour glasses for about 10-15 minutes. The second developer has no issue with any form, any canvas. The hangs seems to be caused by some ethernet activity even though there seems not logical reasons for it. Both have same permissions everywhere. The no problem developer uses sqldeveloper, the other does not.
IT infrastructure guys say no site changes, but even so they both log on to the same M and databases.
any thoughts appreciated.
